[单项选择]Now, more than ever, it doesn’t matter who you are but what you look like.
Janet was just twenty-five years old. She had a great job and seemed happy. She committed suicide. In her suicide note she wrote that she felt "un-pretty" and that no man ever loved her. Amy was just fifteen when hospitalized for eating disorders. She suffered from both anorexia and bulimia. She lost more than one hundred pounds in two months.

[单项选择]
阅读下面文字，完成下列问题。
科学劳动是社会劳动的一般劳动。这种劳动，既取决于今人的协作，又取决于前人的劳动成果。不论古人的还是今人的劳动成果，都表现为一定形式的知识(如图书和情报)。这些知识在进入新的科学劳动中，都是以科学劳动资料的形式出现的。科学家的创造力只有得到科学资料，才能进行创造性劳动，就像“活劳动”只有抓住“死劳动”，才能进行物质劳动一样。知识作为科学劳动资料具有极为特殊的使用价值。
任何物质产品，都会因消费而消失，而知识却在“消费”中永生。任何物质产品交换中都会因为“给了别人，自己就没有了”，而知识却在交流中“给了别人，自己仍然有”。物质产品的消费往往是以其载体灭亡，其信息的毁灭性消费方法进行的，而知识的“消费”过程则不会亡其载体、灭其信息，而是从不同的载体上不断转移，或者由非生命载体向生命载体转移，或者是由生命载体向非生命载体转移。
物质产品的主要属性，在生产它的过程中便一次性地确定下来。牙膏对于消费者来说主要是清洁牙齿，保护口腔；衣服对消费者来说，主要是保暖身体美化生活。但是知识不然，同是一种知识，对于不同知识结构的“消费者”来说，用场各不相同。同一种无线龟知识，家庭主妇的“消费”，仅在于开关电视机；工程师的“消费”，表现为从微电子学的观点，探索改进工艺的途径；科学家的“消费”则表现为使用奇妙的微分方程获得电脑的最新理论。可见，知识的使用价值，表现出明显的多层次现象……
正因为知识的使用价值的再生性，这便带来知识使用价值的第四个特征：馈赠性。知识像一切社会生产力一样，表现了自然的巨大的馈赠性。社会只要把知识生产出来，就无须再费分文了。比如，我们今天利用牛顿定律，无须向英国交税。知识是全人类共同的财富，是大家共享的特殊资源，向自然索取馈赠，最关键是向知识索取馈赠。我们今天建设四个现代化，必须充分利用知识在使用价值上的馈赠性。
以下对文章理解正确的一项是（）。
A. 科学劳动是社会劳动的一般劳动，是一定形式的知识。
B. 知识不会因为消费而消失。
C. 知识的主要属性取决于它的构成。
D. 知识的更新和获得都是免费的。
